Small satellite missions are generally NGSO systems which are not subject to any form of mandatory coordination. For such systems, the provisions of Article 9, Sub-Section IA (Advance publication of information on satellite networks or satellite systems that are not subject to coordination procedure under Section II), are applicable.

How to submit a filing to the Bureau?
• Administrations may submit electronic filings to the Bureau on a CD-ROM or as email file attachement (zipped)
• Each Directory/Folder or zipped file should then contain the following files, as appropriate, for that particular network:
– One Network_Name/Station_Name.mdb file in the SNS file format (this file should contain only ONE network !!)
– One or several files for the submission of graphical data, notes on the diagrams in English only
– One Network_Name/Station_Name.doc file (for any comments pertaining to the network)
Run Spaceval to ensure that there are no fatal errors If there are fatal errors, try to correct them before
submission. If you are unable to get rid of the fatal errors, you can
describe them in the cover letter of your submission, the Bureau will provide assistance to address the errors
Make sure that all required antenna patterns are provided, either by formula or diagrams.
Change extension of .mdb to .itu if there is a problem with your email server
Satellite filings must be submitted by the Administration. 78
Filing should be sent by email to [email protected]
Filing must be confirmed by a fax (no. +41 (22) 730 5785) from an Administration within 7 days
7-year limit to bringing into use and submission of notification, otherwise API will be cancelled, and the entire filing process need to be restarted
Cost recovery No cost recovery fee for amateur satellite service For all other services, containing assignments that are not subject to
coordination ▪ 570 CHF for API ▪ 7030 CHF for Notifications
One free entitlement per year for each Administration
79
Commenting procedures Comments to an API/A should be submitted within 4 months of API (No.9.3)
Comments to be captured using SPACECOM (RES-55)
The Bureau publishes the list of administrations which have sent comments in an API/B special section
Resolution of difficulties Both administrations shall endeavour to cooperate in joint efforts to resolve any
difficulties and shall exchange any additional relevant information that may be available
Either party can request for the assistance of the Radiocommunication Bureau (No.9.3)
In case of difficulties, the administration responsible for the planned satellite network shall explore all possible means to resolve the difficulties without considering the possibility of adjustment to networks of other administrations
If no such means can be found, it may request the other administrations to explore all possible means to meet its requirements.
The administrations concerned shall make every possible effort to resolve the difficulties by means of mutually acceptable adjustments to their networks.
80
According to No.9.2, the only change for NGSO filing that requires a new API would be additional frequency band.
However, it is a good practice to submit a modification to the API any change in characteristics including orbital characteristics, service area (adding earth stations) etc.
This will allow other administrations/operators the chance to submit comments before the modifications are notified for recording in the Master Register.
81
The World Radiocommunication Conference (WRC-12 ) was held in Geneva, Switzerland from 22 January – 17 February 2012
Among the WRC-12 decisions that affect NGSO filing procedures No. 9.2: A new API would be required if
▪ The reference body of the space station is changed
▪ The direction of transmission is changed
New AP4data element B.2bis.a to indicate whether the assignment will be used for continuous/non-continuous transmission (space station only transmits when visible from notified service area)

Registration of frequency assignments with the ITU for small satellites is an obligation of the Administration under the treaty agreement of the Radio Regulations.
This will facilitate a harmonized and coordinated environment for which radio frequency is used on a global basis, minimizing the potential for any harmful interference.
The Radiocommunication Bureau can provide assistance to operators/administrations to achieve the objective of getting their small satellite missions registered, recognized and protected in the Master Register.
